Yes, I posted it. Mackintosh did indeed make them. Rowntrees took over Mackintosh many, many, many years ago but continued to use the brand.
They were a strange combination (chocolates, candies, jellies) but are so fondly remembered by many posters, old and new, to the Forum so they must have been popular.
I was a great fan, and especially loved the Lime Candy one. Lou, our moderator, is also a fan. I'll get my son to help me post another piccie so we can all indulge!
